To all whom 'it may con'eci'ni:

v Be it known that I, JOHN J. HANLON, a citizen of the United States,residing at Troy. county of Rensselaer, and State otl New York, ha'veinvented certain new and useful Improvements in Soot-Ejoctors forrater-Tube Boilers` of which the following is a specification.

The invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompauying drawings, and the referencecharacters marked thereon. which form a part of this specification.Similar characters refer to similar parts in the ,severaPtigurestherein.

Figure 1 of the drawings is a vertical lon- Jitudinal section of awater-tube boiler provided with my novel :soot-rejectingr mechanism.Fig. 2 is a horizontal section of the saine taken on the broken line 2-2in Fig. 1. Fig. El is a horizontal section of one of the soot-cjectingnozzles detached.

The principal object of my invention is to effectively remove from timeto time accumulations of soot, ashes, &c., from a water-tutu! boilerwithout injury to the brick-work incasing the boiler.

Other objects will appear in connection with the Followingr description.

.teferring to the drawings herein thc invention is shown in preferredform, 1, represents the cylindrical body of the boiler, from whichdepend the front, water-le; r, 2, and roar water-leg` Il, saidwater-legs being connected together by a series of water-tubes, 4, intho usual manner. Above the uppermost row of tubes, 4, is the usualbaille-plate, 5. formed by tiles of tiro-brick extendingl from the rearwater-leg to within a short distance of the front water-leg, leavingthcrcat an opening. t3, from tbc space coutainiug thc w"itcr-tHbes upinto thc space. T between the baille-plate, 5, cylindrical body, 1, andthe setting of the boiler,- which space 'communicates with the stack 8.ln lik(l manner above the lam'ermost row of tubes is a baille-plate. il,extending from the front water-leg to within a short distance of thcYrear water-leg, leaving thcrcat an opening, 10, leadingr from thccomlmstion-chamber, 11, upward into the space between tbe two bailleplates.

0u opposite sides of the boiler, adjacent tu tbc opening, 10, l mount inthe boilersettinga pair of nozzles, l2, each in connection with asupply-pipe, 19, leadin from a suitable supply or' steam or air un erpressure, which source of supply may be the body, 1, of the boiler. Eachof the nozzles, 1:2, is provided with a lurality of inwardly andforwardly extending nipples, 13, the nipples of said two nozzles being'directed eonvergently forward toward a `common point just above theopening, 10, whereby the jets or steam or air ejected under 'pressurefrom said nipples are caused to impinge, those from one nozzle againstthose from the other, while causing, a forward currentJ of greatvelocity which not only drives before it toward the front end of theboiler soot accumulated upon the several tubes, but also causes aforced-np draft through the o cning, 10, adapted to force u )ward throngsaid openinfr accumulations o' soot. or ashes on the bri ge-wall, 14, orwalls of the combustion-chamber I1. ln like manner I mount in theboiler-settin \,l on opposite sides of, and just above, the opening, 6,a similar pair of nozzles, 15, each connected with a supply-pipe, 16,lending from the boiler-body or other source of supply of steam or airunder ressnre, each of said nozzles, 15, being rovided with a plu ralityof forwardly an rearwardly extending nipples, 17, the nip les of saidtwo nozzles, 15, being directed) convergenlly rearward just above theopeninff, 6, whereby the jets of steam or air ejeter under pressure fromsaid nipples, 17, are caused to impingc, those from one nozzle againstthose from the other, while causiiw a rearward current of great velocitywhich not only drives before it to Iard the, rear cud of the boiler sootaccumulated upon the baille-plate, 5, body, l, ot' thc boiler, and wallsof the lmiler-setting, but also greatly accelerates thc forced-up draftthrough the opening, wbcrcby the nozzles, tf, coiipcratc with thelnozzles, l2, to eject accuundationrI of soot and ashes from thcwater-tubes. 'lbc members ot' each pair of oppositcly-locidednozzlc-outlels which converge toward a common point preferably occupysubstantially the saine horizontal plane just above the draft-openying.- Hy having the oppositely located nipples directed convergently andobliquely,tbe nnpugemcnt. of thc jets from one nozzle upon thosel fromthe other oppositely located nozzle prevents the jets from striking theside walls of the boiler-setting at. u favorable angle, and withsuiiicient force, to injure or wear away said'walls. The reinoxed sootand ashes are carried up the stack by the forced draft created by thecombined action of the nozzles, 12 and 15.. A

By admitting to the Ynozzles steam or air under pressure for a period ofa few minutes each day, the tubes and walls of the boiler can be kept'practically clean and free from accumulations of soot and ashes.

What I claim as new and desire to secure by Letters Patent isl. In awater-tube boilerQthe combination with the boiler-body; Watertubes; andboiler-setting; of a bathe-plate partly inclosing the tube-containingspace and provided with a draft-opening; a pair of ejectornozzlesmounted in the setting on opposite sides of one of saiddraft-openings, said nozzles having nipples convergently inclined towardeach other in the direction of the draft, and having; their outlets insubstan-A tially the saine horizontal plane justl above saiddraft-opening.

2. In a Water-tube boiler, the combination with the boiler-body;watertubes; and

boiler-settingg of upper and lower baieplates partly inclosing thetube-containing space, said upper battle-plate being provided with atirait-opening at its front end, and said lower baille-plate with adraft-opening at its rear end; a pair ot ejector nozzles mounted in thesetting on opposite sides of, and just above, the draft-opening in theupper hama-plate, and having nippleseonvergentlj: and rearwardlyluclined, with their outlets in substantially the same horizontal plane;and a pair of nozzles mounted in the setting on opposite side-2: of, andjust above, said draft-opening in the lower initiieplate, and havingnipples Courel-gently and forwardly inclined, with their outlets insubstantially the saine horizontal plane.

3. In a water-tube boiler, the combination with the boiler-setting; of npair of ejector nozzles mounted on opposite sides of ,the space inclosedby the setting, and having their outlets convergent toward eachother inthe direction of 'the draft through' said space and toward a commonpoint.

lin testimony whereof, 'have'hereunto set my hand this 14th day of .May,1999.
